The cloud-native asset model (CNAM) format transforms an UP42 asset from a tasking or a catalog order into individual geospatial features available for immediate download.
CNAM also standardizes the following types of files to enable easier integrations:
- Raster data is converted into cloud optimized GeoTIFFs (COGs).
- Vector mask files are converted into GeoJSONs.
Regardless of provider or delivery format, all order assets that fall within the criteria are transformed into a standard model.
-
Asset delivery time
CNAM is only applied to assets added to storage starting in 2023. Assets added prior to 2023 aren’t transformed and aren’t retrievable through STAC.
-
Supported collections
Not all geospatial collections are supported.
The transformed data is retrievable through STAC. Here is a mapping explaining the relationship between STAC objects and asset-related concepts:
-
UP42 order delivery ⟷ STAC collection
A STAC collection is an UP42 asset you received after a completed order. -
Scene with unique spatiotemporal extent ⟷ STAC item
A STAC item is an individual scene that represents inseparable data and metadata. A STAC item has a unique spatiotemporal extent, that is, has one AOI and acquisition time in its characteristics. -
Individual geospatial feature ⟷ STAC asset
A STAC asset is a geospatial feature of a STAC item. For example, bands in an optical image, thumbnails, or metadata files.
